I'm not sure yet, Charlotte was 2yrs 4 months when she trained, George is 2yrs 1 month and he knows when he is weeing and pooing and when he's dirty but wont train as yet. We keep trying to get him more familiar with the potty but he is frightened of it so we keep leaving it. (In fact tpday is another 'try' day, he loves wearing his underpants

)
Charlotte was more advanced in talking, by the age George is now, she could have a full conversation with us, George can't but I think its the way he's made lol, he trys his best but he seems to be still getting the hang of the sounds of words
Like Aaralyn, Tammy, Charlotte has come down with her T-shirt on back-to-front this morning lol but she can dress herself and choose her own clothes, but George also likes to help pick out clothes and can put his arms through his tops himself and put his legs in the holes in his pants.
